Book 3 — Box Cover without Hinges

Box Cover Using Pins Instead of Hinges to Keep It in Place

Two ordinary boxes may be fitted together as one without using hinges, if nails or screws are inserted at points along the edges so that they will slip into holes bored at corresponding points in the edges of the other box. The nail heads or screw heads should be filed off or cut off after being placed in position.

¶All metal patterns should be thoroughly cleaned with a stiff brush having plenty of beeswax on it and dipped in powdered plumbago. Brush the pattern well, and it will draw easily and make a smooth casting.
